The suspects were brought to Vatan Police Station following routine health checkups.

Meanwhile, police has reportedly carried out anti-terror raids in eight provinces and have detained an unspecified number of suspects.

The operations follow a deadly terrorist attack in the capital carried out by the PKK and claimed the lives of 35 civilians.

The Interior Ministry said in a written statement on Tuesday that the suicide car bombing in Ankara was conducted by 24-year-old Seher Çağla Demir. She joined the PKK terrorist organization in 2013 and was allegedly trained by the People's Protection Units (YPG) in Syria
